1. Does old map built for TC:E will run fine on new TC:CQB engine ?
2. Does TC:CQB will provide any new kind of entities ?
3. Does old textures branch will stay ?
4. Does TC:CQB need any new urban textures ? I will be glad if I can help on it.

Anyway, if CQB will require new map format can we use new prefix:
obj_delta -> cqb_delta
